Hello Mike
This is the problem I have with New Zealand roads, such beautiful scenery but the turn ins are very scarce and you cannot be 100% sure that where you do stop that some nutter on the road will not wallop into you and your car.
A real shame because I have had the same problem, the roads are not wide enough for just pulling up anywhere and plus once that light is up it does not stay long. The light and clouds are awesome, obviously a stronger composition would be to head further down the road ad use the bend of this road to use as a vanishing and strong perspective point, therefore eliminating the bush more on the left. Excellent natural colours,
Jim
